TOOTHBRUSH HAVING A DUAL ROTARY BRUSHING SYSTEM

摘要

A mechanical toothbrush having a dual rotary brushing system, comprising a body (1) forming a handle, and a head (4) attached to said handle and provided with two adjacent counter-rotating cylindrical brushes (5, 5') with substantially parallel axes. Each of said brushes (5, 5') is driven by a flexible shaft (9, 9') located in the head (4) and supported at least at the distal end by a bearing (16) on a supporting member (10) enabling the brushes to be moved apart and resiliently bringing them back together.
